[0028] A dual power automatic transfer switch device, such as Figure 1-Figure 8 As shown, it includes a control mechanism, and a mounting plate 18 and a mounting plate 2 19 are fixedly connected on both sides of the control mechanism, and an actuator 21 is fixedly connected between the mounting plate 18 and the mounting plate 2 19 on a side away from the operating mechanism assembly 15. The mounting plate 18 and the mounting plate 2 19 fix and compactly install the control mechanism and the actuator 21. The actuator 21 and the control mechanism are driven to cooperate with each other, and the control mechanism is placed in front to drive the actuator 21 to operate.

[0029] The control mechanism includes an operating mechanism assembly 15, and an operating panel 9 is fixedly connected to a side of the operating mechanism assembly 15 away from the actuator 21. An electronic control box 11 with a switch assembly such as a plurality of micro switches is fixedly connected to the upper end of the operating mechanism assembly 15. A control terminal 10 for connecting a circuit is fixedly connected to the upper end of the electronic control box 11. A closing auxiliary assembly 16 for detecting the closing status is fixedly connected to one side of the operating mechanism assembly 15 close to the mounting plate 18, and an interlaced connecting rod mechanism 3 is rotatably connected to the other side for driving and cooperating with the actuator 21.

[0030] The operating mechanism assembly 15 of the dual power automatic transfer switch electrical appliance is placed in front to reduce the overall left and right length of the electrical appliance. The length is only the product of the phase spacing and the number of poles. The front operation, the rear actuator 21, and the wiring at the back are arranged. The control mechanism adopts a modular structure. The interior of the operating mechanism assembly 15 also adopts a modular structure, which is convenient for installation and maintenance, and meets the requirements of modern power systems for miniaturization, modularization, and high reliability of equipment.

[0031] The operating mechanism assembly 15 includes a frame 17, and a closing lock mechanism 2 is rotatably connected inside the frame 17. A closing electromagnet assembly 6 is fixedly connected to the bottom of the inner wall of the frame 17. A closing drive mechanism 5 is hinged on the upper end of the closing electromagnet assembly 6. The closing drive mechanism 5 is clamped with the closing lock mechanism 2, and one end of the closing lock mechanism 2 is driven and cooperated with the staggered connecting rod mechanism 3.

[0032] like Figure 3 , Figure 7 As shown, the closing electromagnet assembly 6 is energized to attract the closing drive mechanism 5, causing the closing drive mechanism 5 to rotate, driving the closing lock mechanism 2 to rotate, and the closing lock mechanism 2 drives the staggered connecting rod mechanism to operate, thereby causing the actuator 21 to operate. This is the automatic switch mode.

[0033] A manual front operating mechanism 1 is rotatably connected in the frame 17 , one end of the manual front operating mechanism 1 is hinged to the closing drive mechanism 5 , and the manual front operating mechanism 1 cooperates with the control panel.

[0034] like Figure 3 , Figure 7 As shown, the control panel slides to a certain state, and the manual front operating mechanism 1 is plugged into the handle to rotate. One end of the manual front operating mechanism 1 drives the closing driving mechanism 5 to rotate, and drives the closing lock mechanism 2 to rotate. The closing lock mechanism 2 drives the staggered connecting rod mechanism to operate, thereby operating the actuator 21. This is the manual switch mode.

[0038] like Figure 4 , Figure 6 As shown, the staggered linkage mechanism 3 operates to pull the driving arm 24, so that the driving arm 24 pulls the driving rod 22 to rotate, and the driving rod 22 penetrates the actuator 21 to drive the actuator 21 to switch the opening and closing states. The side frame 20 is used to protect the driving arm 24.

[0039] A side plate 4 is fixedly connected to one side of the frame 17 . A V-shaped groove is formed through the side plate 4 . One side of the staggered linkage mechanism 3 is slidably connected to the V-shaped groove.

[0040] like Figure 4 , Figure 7 As shown, the V-shaped groove limits the running path of the staggered linkage mechanism 3 and facilitates the connection between the driving arm 24 and the staggered linkage mechanism 3.

[0041] The working principle of a dual power automatic transfer switch electrical appliance provided by the utility model is as follows:

[0042] The operating mechanism assembly 15 of the dual power automatic transfer switch electrical appliance is placed in front to reduce the overall left and right length of the electrical appliance. The length is only the product of the phase spacing and the number of poles. The front operation, the rear actuator 21, and the wiring at the back are arranged. The control mechanism adopts a modular structure. The interior of the operating mechanism assembly 15 also adopts a modular structure, which is convenient for installation and maintenance, and meets the requirements of modern power systems for miniaturization, modularization, and high reliability of equipment.
